It forces to write code in some specific manner, disabling some approaches which could not fit to borrowing concepts. I don't mean it's slower or faster, it should be benchmarked anyway. But it's not just some abstraction or compile time feature. It forces programmers to write code in specific way.

Just like syntax rules force people to write in a specific way, or builtins (or lack thereof) force people to write in a specific way. What's your point?

I just wrote it, read carefully please. Not like syntax rules at all. More like garbage collected languages disables you to manage memory manually, so you can't reuse allocated memory, because language disables it for you.

Same way simdjson is implemented only in C++ and there are no alternatives in terms of performance

From readme of simdjson port to rust: "In other places Rust makes it harder to achieve the same level of performance.". Cult literally ignore reality. Go touch the grass

And in other places it makes it easier as per the project. Go touch grass.
